Monsanto, a chemical firm owned by German pharmaceutical company Bayer, has been ordered to pay $857 million (£676 million) to seven individuals who claimed to have suffered health issues due to chemicals leaking from light fixtures at a US school. The plaintiffs, including former students and parent volunteers, asserted that exposure to polychlorinated biphenyls (PCBs) at the Sky Valley Education Centre in Washington state caused neurological and endocrine system problems.
